Big Mike

Alerts features of NT7 using an indicator, like TrendLineAlertCustom in Downloads, uses an Extended Line as the trigger and the Alert, Print and Say functions to communicate the message.

The following code is necessary:

Code

                            foreach (IDrawObject draw in DrawObjects)
     {
        if ((draw.Tag.StartsWith(&quot;Trend Line&quot;)||draw.Tag.StartsWith(&quot;Resistance&quot;)||draw.Tag.StartsWith(&quot;Support&quot;)) &amp;&amp;draw is ILine)
          {
           ILine drawnLine = (ILine) draw;    
           if(  drawnLine.DrawType==DrawType.ExtendedLine||drawnLine.DrawType==DrawType.Line||drawnLine.DrawType==DrawType.HorizontalLine )
            {
                 LineName=draw.Tag;
                currentY= drawnLine.StartY+(drawnLine.StartBarsAgo)/(-drawnLine.EndBarsAgo+drawnLine.StartBarsAgo+.0000001)*(drawnLine.EndY-drawnLine.StartY);
    Values[].Set(currentY);
            }  
    //Price rising above the manually drawn Trend Line        
            if((Close[]-currentY&gt;&amp;&amp;lastprice-currentY&lt;=))
            {    Alert(&quot;Alert&quot;, Priority.High, InstrumentName+&quot;: $&quot;+Close[]+&quot;, Rising Above Trendline &quot;+LineName, soundFileR, 1, Color.Black, Color.Lime);
                Print(&quot;TrendLineCustom &quot; +InstrumentName+&quot;: $&quot;+Close[]+&quot;, Rising Above  &quot;+LineName);
                if(!over)Say(InstrumentName+&quot; crossing ABOVE &quot;+LineName+&quot;   at   &quot;+Close[]);
                over=true;
            }
